New Years Playlist?

We've decided to follow the same plan as last year - Meet at our favorite place, stay until about 1130 when the unknowns run it over. Then trip the half a block back to the Best Friend's place with our Entourage and ring in Midnight at the apartment.

So we need a playlist for the 1130 and on soiree! Recommendations of your favorites from 2009 - Black Eyed Peas, Beyonce, Lady Gaga, and Miley already chiseled in stone
